Area of rectangle = length * width

A = (2 2/9 yd) * (3 2/5 yd)

Convert both mixed numerals into fractions.

A = (20/9 yd) * (17/5 yd)

A = (20 * 17)/(9 * 5) yd^2

A = (4 * 17)/(9) yd^2

A = 68/9 yd^2

A = 7 5/9 yd^2

If x + y = 2 and x - y = 6, solve for x and y.
anyanavicka [17]

Answer:

Step-by-step explanation:

Givens

x + y = 2

x - y = 6

Solution

Just add the two equations together. The y's will drop out.

x + y = 2

<u>x - y = 6 </u>             Add

2x = 8                 Divide by 2

2x/2 = 8/2          Combine

x = 4                   Substitute x = 4 into the top equation

x + y = 2

4 + y = 2             Subtract 4 from both sides

4-4+y=2-4          Combine

y = - 2    

Answer

x = 4

y = -2

Which graph is the result of reflecting f(x) = (8)x across the y-axis and then across the x-axis?
VARVARA [1.3K]
Refrection of a function across the y-axis, changes the sign of x in the function.

Thus, given the function:
f(x)=(8)^x
Refrection of the function across the y-axis will result in the function:
g(x)=(8)^{-x}

Refrecting a function across the x-axis, changes the sign of the function.

Thus, refrecting the function:
g(x)=(8)^{-x}
across the x-axis will result in the function:
h(x)=-(8)^{-x}

The graph of f(x)=(8)^x and h(x)=-(8)^{-x} is attached.
The green curve represents the graph of the function f(x)=(8)^x, while the orange curve represents the graph of the function h(x)=-(8)^{-x}.
